transmission Ram 1500 2009 Service Manual

WARNING! (Continued)
•Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
When hauling cargo or towing a trailer, do not overload
your vehicle or trailer. Overloading can cause a loss of
control, poor performance or damage to brakes, axle,
engine, transmission, steering, suspension, chassis struc-
ture or tires.
Safety chains must always be used between your vehicle
and trailer. Always connect the chains to the frame or
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow vehicle.
Put the tow vehicle transmission in PARK. With four-
wheel-drive vehicles, make sure the transfer case is not in
NEUTRAL. Always, block or chockthe trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer so that the following four ratings
are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized (This
requirement may limit the ability to always achieve the
10% to 15% range of tongue weight as a percentage of
total trailer weight).
406 STARTING AND OPERATING

WARNING!
Any work done to the vehicle’s electrical system or
wiring should be performed by a qualified automo-
tive technician. If done improperly it may cause
damage to the electrical system wiring and could
result in serious or fatal injury.
Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, select
“TOW/HAUL” mode (if equipped) or select a lower gear
using the Electronic Range Select (ERS) feature.NOTE:
Using “TOW/HAUL” mode or a lower gear
range while operating the vehicle under heavy operating
conditions will improve performance and extend trans-
mission life by reducing excessive shifting and heat build
up. This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you regularly tow a trailer for more than
45 minutes of continuous operation. Refer to the “Main-
tenance Schedule” in Section 8 for the proper mainte-
nance intervals.
NOTE: Check the automatic transmission fluid level
before towing.Tow/Haul
To reduce potential for automatic transmission overheat-
ing, turn the “TOW/HAUL” feature ON when driving in
hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) feature) on more severe
grades.
410 STARTING AND OPERATING

Electronic Speed Control — If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put the trans-
mission in NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
SNOWPLOW
NOTE: Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a colli-
sion resulting in serious injury or death.5
STARTING AND OPERATING 411

CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in an acci-
dent. Do not expect that the airbag will perform as
described earlier in this manual
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
Recreational Towing – Two-Wheel Drive Models
Recreational towing of two-wheel drive models is not
allowed.Towing with the rear wheels on the ground can
result in severe transmission damage.
412 STARTING AND OPERATING

Recreational Towing – Four-Wheel Drive Models
CAUTION!
Failure to follow these requirements can cause severe
damage to the transmission and/or transfer case.
NOTE: The electronic shift transfer cases must be
shifted into NEUTRAL for recreational towing. The trans-
mission must be shifted into PARK for recreational
towing. Refer to the following for the proper transfer case
NEUTRAL shifting procedure for your vehicle.
Recreational Towing Procedure — Electronic Shift
Transfer Case — If Equipped
Use the following procedure to prepare your vehicle for
recreational towing:
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL before recre-
ational towing to prevent damage to internal parts.
